Speedometer Cable Question: Aftermarket or “New Chrysler”?

I am looking for a new speedometer cable, I noticed that Year one has three of them listed here.

Does any one have any experience with changing the speedometer cables? The project car it is going to be for is a '74 Duster with a 440/727. What do they mean "new chrysler"? I am going to assume that the "aftermarket" cable is a cheap repop.

Any advice is greatly appreciated!
